Referring to fig. 1 and 2, fig. 1 is a schematic structural view of an embodiment of an evaporation source and a limiting plate in the prior art, and fig. 2 is a schematic structural view of an embodiment of a display panel in the prior art.
In the actual vapor deposition process, since the vapor deposition source 210 forms one vapor deposition cloud in the longitudinal direction of the vapor deposition source 210, the vapor deposition angle of the vapor deposition material cannot be controlled in the longitudinal direction of the vapor deposition source 210, and the purpose of controlling the emission angle of the vapor deposition material can be achieved by the limiting plates 220 on both sides in the moving direction of the vapor deposition source 210 (i.e., the scanning direction of the vapor deposition source 210). Thus, in the prior art design as shown in fig. 2, the conductive enclosure structure 110 is able to contact the cathode 125 in the direction of movement of the evaporation source 210; however, the conductive barrier structure 110 does not overlap the cathode 125 of the sub-pixel 120 in the longitudinal direction of the vapor deposition source 210.
Referring to fig. 3, fig. 3 is a schematic structural diagram of a first embodiment of a display panel according to the present application, and fig. 4 is a schematic sectional view of the display panel in fig. 3 along A-A direction.
Based on the foregoing vapor deposition technology, the present application provides a display panel 100, where the display panel 100 includes a driving substrate 140 (as shown in fig. 8), a pixel defining layer 126, a conductive enclosure structure 110, and a plurality of sub-pixels 120. The pixel defining layer 126 is disposed on the upper surface of the driving substrate 140. The conductive enclosure structure 110 is disposed on a portion of the surface of the pixel defining layer 126, and the portion of the pixel defining layer 126 protruding from the surface is disposed to form the pixel accommodating region 111. The plurality of sub-pixels 122 are arranged in the pixel accommodating region 111 along the long side direction of the conductive enclosure structure 110. Wherein the conductive enclosure structure 110 encloses and accommodates a plurality of sub-pixels 120, each sub-pixel 120 includes an anode 123, an organic light emitting layer 124, and a cathode 125. The anode 123 is disposed on the surface of the driving substrate 140 within the pixel accommodating region 111. The organic light emitting layer 124 is disposed on the anode 123. The cathode 125 is vapor-deposited on the surface of the organic light-emitting layer 124 by a vapor deposition source. The cathodes 125 are disposed in contact with the long sides of the conductive enclosure structure 110 to conduct between the cathodes 125 of the plurality of sub-pixels 120 in the conductive enclosure structure 110 through the long sides of the conductive enclosure structure 110. In the process of evaporating the cathode 125, the moving direction of the evaporating source intersects with the long side direction of the conductive enclosure structure 110. Compared with the prior art that one conductive enclosure structure 110 is provided for each sub-pixel 120, the display panel 100 provided by the application can save the conductive enclosure structure 110 between the sub-pixels 120 in the long side direction of the conductive enclosure structure 110, further simplify the conductive enclosure structure 110, reduce the spacing between the sub-pixels 120 in the conductive enclosure structure 110, thereby increasing the aperture ratio of the display panel 100, further improving the display effect of the display panel 100, and greatly reducing the cost for manufacturing the display panel 100.
It should be noted that, the longitudinal direction of the conductive enclosure structure 110 of the present application is the longitudinal direction of the vapor deposition source 210 in fig. 1.
It can be appreciated that, in this embodiment, the plurality of sub-pixels 120 are disposed in the same conductive enclosure structure 110, so as to achieve the purpose of increasing the evaporation effective area of the pixel light emitting region.
The driving substrate 140 is used for driving the sub-pixels 120 to emit light. The pixel defining layer 126 is disposed between the sub-pixels 120 to space the anodes 123 between the sub-pixels 120, so as to prevent the anodes 123 of the adjacent sub-pixels 120 from being mutually conducted, thereby affecting the display effect of the display panel 100.
The conductive enclosure structure 110 includes a conductive body 112 and an insulator 113, the insulator 113 is covered on one side of the conductive body 112 far away from the driving substrate 140, and the cathode 125 is electrically connected to the conductive body 112. Specifically, the cathode 125 of each sub-pixel 120 is in contact with and is electrically connected to the long-side conductor 112 of the conductive enclosure structure 110 where the sub-pixel 120 is located, so that the cathodes 125 of the sub-pixels 120 in each conductive enclosure structure 110 are electrically connected to each other through the long-side conductor 112 of the conductive enclosure structure 110.
Referring to fig. 5, fig. 5 is a schematic structural diagram of two adjacent conductive enclosure structures in the display panel according to the present application.
The conductive enclosure structure 110 is an annular structure, and encloses a pixel accommodating area 111. As shown in fig. 5. In the short side direction of the conductive enclosure structure 110, a plurality of conductive enclosure structures 110 are arranged side by side, and two adjacent conductive enclosure structures 110 share the same long side of the conductive enclosure structure 110. The short side direction of the conductive enclosure structure 110 is parallel to the moving direction of the vapor deposition source 210.
In the present embodiment, the conductive enclosure structure 110 has a rectangular cross section in a direction parallel to the driving substrate 140. In other embodiments, the conductive enclosure structure 110 may be parallelogram-shaped in cross-section in a direction parallel to the drive substrate 140.
The conductive enclosure structure 110 encloses and accommodates a column of the sub-pixels 120, that is, a plurality of the sub-pixels 120 in one pixel accommodating area 111 are arranged in a column, and a column direction of the plurality of sub-pixels 120 is parallel to a long side direction of the conductive enclosure structure 110. The color of the plurality of subpixels 120 enclosed in a single conductive enclosure structure 110 may be the same or different.
In this embodiment, the color of the plurality of sub-pixels 120 enclosed in the single conductive enclosure structure 110 is the same. The number of the sub-pixels 120 enclosed and accommodated by each conductive enclosure structure 110 is the same, so that the sub-pixels 120 can be orderly arranged along with the conductive enclosure structures 110 when the conductive enclosure structures 110 are arranged, and the preparation of the display panel 100 can be simplified.
As shown in fig. 5, two adjacent conductive enclosure structures 110 share the same long side of the conductive enclosure structure 110, so as to ensure that the pitches between the adjacent sub-pixels 120 in the short side direction of the conductive enclosure structure 110 are equal, which is beneficial to the uniformity of display of the display panel 100. Secondly, two adjacent conductive enclosure structures 110 share the same long side of the conductive enclosure structure 110, so that the conductive enclosure structures 110 can be mutually contacted and conducted, and further, cathodes 125 of each sub-pixel 120 in the conductive enclosure structure 110 are arranged in contact with the long side of the conductive enclosure structure 110, so that cathodes 125 of sub-pixels 120 in different conductive enclosure structures 110 can be mutually conducted, wiring can be reduced, transmission stability of signals of the cathodes 125 between a plurality of sub-pixels 120 can be guaranteed, and display uniformity of the display panel 100 is facilitated.
In this embodiment, only two conductive enclosure structures 110 are listed to describe the arrangement manner in which adjacent conductive enclosure structures 110 share the same long side of the conductive enclosure structure 110. The sub-pixels 120 surrounded by one conductive enclosure structure 110 of two adjacent conductive enclosure structures 110 are all first sub-pixels 121, and the sub-pixels 120 surrounded by the other conductive enclosure structure 110 are all second sub-pixels 122. The first subpixel 121 and the second subpixel 122 are different in color. It should be appreciated that the display panel 100 of the present application includes more conductive enclosure structures 110, and more subpixels 120 of different colors.
It should be understood that, if the number of conductive barrier structures 110 is plural in the column direction of the sub-pixels 120, two adjacent conductive barrier structures 110 share a short side of the same conductive barrier structure 110 in the column direction of the sub-pixels 120, so as to avoid that the spacing between adjacent sub-pixels 120 is too large in the long side direction of the conductive barrier structure 110, which affects the display uniformity of the display panel 100.
The display panel 100 includes a plurality of sub-pixel groups 127 of different colors, each sub-pixel group 127 including a plurality of sub-pixels 120 of the same color. The single sub-pixel group 127 is located in the single pixel accommodating area 111, and a plurality of sub-pixel groups 127 of different colors are alternately arranged in sequence along the short side direction of the conductive enclosure structure 110.
It will be appreciated that one sub-pixel group 127 is enclosed and accommodated within one conductive enclosure structure 110. The plurality of same-color subpixels 120 in the subpixel group 127 are arranged along the long side direction of the conductive enclosure structure 110. The color of the subpixels 120 in the adjacent two subpixel groups 127 is different. The plurality of sub-pixels 120 are arranged in an array, and the sub-pixels 120 with different colors are alternately arranged in sequence along the short side direction of the conductive enclosure structure 110, and are repeatedly arranged along the long direction of the conductive enclosure structure 110.
In the sub-pixel group 127 within each conductive enclosure structure 110, the sub-pixels 120 located at the short-side end of the conductive enclosure structure 110 are defined as end sub-pixels 128, and the remaining sub-pixels 120 in the sub-pixel group 127 except for the end sub-pixels 128 are defined as intermediate sub-pixels 129. The organic light emitting layer 124 of the end sub-pixel 128 extends to be disposed in contact with the short side of the conductive enclosure structure 110 at one end, and is connected to the organic light emitting layer 124 of the adjacent intermediate sub-pixel 129 at the other end, and covers the pixel defining layer 126 between the end sub-pixel 128 and the adjacent intermediate sub-pixel 129. The organic light emitting layers 124 of the intermediate sub-pixels 129 are connected to each other and cover the pixel defining layer 126 located between the adjacent intermediate sub-pixels 129.
That is, the subpixel group 127 within each conductive enclosure structure 110 includes two end subpixels 128 and at least one middle subpixel 129. In each sub-pixel group 127, only the end sub-pixels 128 are disposed in contact with the short sides of the conductive enclosure structure 110, and the middle sub-pixels 129 are disposed in contact with the long sides of the conductive enclosure structure 110. In the pixel accommodating area 111 surrounded by each conductive enclosure structure 110, the cathodes 125 of the end sub-pixels 128 and the cathodes 125 of the middle sub-pixels 129 are connected to each other and form a piece, and cover the pixel defining layer 126 surrounded by the conductive enclosure structure 110. Similarly, in the pixel accommodating region 111 surrounded by each conductive enclosure structure 110, the organic light emitting layer 124 of the end sub-pixel 128 and the organic light emitting layer 124 of the middle sub-pixel 129, and the organic light emitting layer 124 of the middle sub-pixel 129 are connected to each other to form a single piece and cover the pixel defining layer 126 surrounded by the conductive enclosure structure 110. Compared to the prior art in which one conductive enclosure structure 110 is configured for each sub-pixel 120, the structural design can reduce the spacing between sub-pixels 120 and increase the aperture ratio of the display panel 100 by disposing a plurality of sub-pixels 120 with the same color in one conductive enclosure structure 110, and defining the spacing between the sub-pixels 120 with the same color in the conductive enclosure structure 110 only by the pixel definition layer 126 between the sub-pixels 120.
Referring to fig. 6 to 9, fig. 6 is a schematic structural diagram of a second embodiment of the display panel according to the present application, fig. 7 is a schematic sectional view of the display panel in fig. 6 along the B-B direction, fig. 8 is a schematic structural diagram of an embodiment of the display panel according to the present application, and fig. 9 is a schematic sectional view of the display panel in fig. 8 along the C-C direction.
The second embodiment of the display panel 100 provided by the present application is substantially similar to the first embodiment of the display panel 100 provided by the present application in that: a plurality of barrier structures 130 extending along the short sides of the conductive enclosure structure 110 are also disposed within each pixel receiving area 111.
In this embodiment, a plurality of blocking structures 130 extending along the short sides of the conductive enclosure structures 110 are further disposed in each pixel accommodating area 111, and the blocking structures 130 are attached to a side surface of the pixel defining layer 126 between the sub-pixels 120 in the same conductive enclosure structure 110, which is far away from the driving substrate 140, and are alternately disposed with the sub-pixels 120 in the corresponding conductive enclosure structure 110 along the long side direction of the conductive enclosure structure 110, so that adjacent sub-pixels 120 in the sub-pixel group 127 are disposed at intervals.
The barrier structure 130 includes at least one of an organic material, an inorganic material, and a metal material.
The blocking structure 130 has at least one of a rectangular, trapezoidal, or tapered cross section in a direction perpendicular to the driving substrate 140. In the long side direction of the conductive enclosure structure 110, the width of the blocking structure 130 is smaller than the interval between the sub-pixels 120 in the same conductive enclosure structure 110, so as to prepare the blocking structure 130, and prevent the blocking structure 130 from occupying the pixel accommodating area 111 to affect the display effect of the display panel 100.
